Uma Maheswara Rao G commented on HADOOP-4048:
---------------------------------------------
{code}
// clean up all calls
if (closeException == null) {
if (!calls.isEmpty()) {
LOG.warn(
"A connection is closed for no cause and calls are not empty");
// clean up calls anyway
closeException = new IOException("Unexpected closed connection");
cleanupCalls();
}
} else {
// log the info
if (LOG.isDebugEnabled()) {
LOG.debug("closing ipc connection to " + server + ": " +
closeException.getMessage(),closeException);
}
// cleanup calls
cleanupCalls();
}
{code}
In Trunk, when closing the client, this is the peice of code will execute.
You mean, we can add the log in else part also when the calls are not empty?
